Apparently a queen cannot cover another queen except if it is the same color (i.e. one of them was created by a joker). Can the admins please point where in the problem statement is stated this? I lost plenty of time to figure it out and (as far as I see from the discussion board) other people have had the same problem. Please add it to the problem statement to reduce future confusion - the statement is confusing enough as it is...
